Nvidia Pumps $4 Billion into Photonics for AI Revolution
Nvidia announced a combined $4 billion investment into two U.S. photonics companies—$2 billion in Lumentum and $2 billion in Coherent—aimed at strengthening research pipelines and supply chains for AI infrastructure. The agreements include multi-year strategic arrangements with multi‑billion dollar purchase commitments and future capacity or access rights for advanced laser, silicon photonics and optical networking components. Nvidia said the collaborations will advance silicon photonics to support next‑generation, gigawatt‑scale AI data centers. Shares of Lumentum and Coherent rose sharply on the news, and Nvidia stock also gained. Jensen Huang, Nvidia’s founder and CEO, framed the moves as securing sophisticated silicon photonics for large‑scale AI factory builds.
Nvidia's sizable investment secures photonics supply and capacity for AI infrastructure, which could accelerate deployment and reduce bottlenecks for large‑scale AI data centers relevant to broader technology ecosystems.

Nvidia Invests Billions in Photonics for AI
Nvidia has committed at least $6.5 billion since March 2026 into companies developing photonics — the use of light to transmit data — as it seeks to overcome energy and bandwidth bottlenecks in AI infrastructure. Investments include a $2 billion program into Lumentum, Coherent and Marvell, a $500 million commitment to Corning, and participation in Ayer Labs’ $500 million Series E. CEO Jensen Huang said at GTC that silicon photonics capacity must be scaled well beyond current global supply. Analysts say photonics can reduce energy costs and enable rack-scale GPU connectivity, but large-scale deployment faces manufacturing and packaging yield challenges; some experts expect broad adoption in the second half of the decade (around 2028+).
Nvidia Boosts Nebius Stock 16% with $2 Billion Investment
Nvidia announced a $2 billion investment in Nebius Group and a strategic collaboration to deploy AI infrastructure, manage fleets, support inference workloads, and design AI factories. As part of the deal Nvidia will give Nebius early access to its next-generation accelerated computing platform. Nebius said it aims to deploy more than five gigawatts of capacity by the end of 2030. Nvidia CEO Jensen Huang described the partnership as scaling the cloud for rising global demand for intelligence; Nebius CEO Arkady Volozh said the company was built specifically for AI workloads rather than adapted from general-purpose cloud. The announcement follows several other recent $2 billion Nvidia investments in companies such as Lumentum, Coherent, Synopsys and CoreWeave, and sits alongside Nvidia’s larger capital commitments to AI ecosystem players including OpenAI and Anthropic.
Nvidia's AI Investments Reach $99 Billion, Becoming Major Backer
Nvidia has become one of the world's largest corporate backers of AI companies, with its equity investments soaring to $99 billion as of July 26, up from $7 billion a year earlier. The chip giant committed over $40 billion in 2026 alone, financing rounds across the AI stack including frontier labs, neoclouds, and photonics startups. Recent deals include a $30 billion investment in OpenAI, a $2 billion investment in CoreWeave, and a $2 billion investment in Nebius. Nvidia also announced plans to acquire Hugging Face for $12.9 billion. The company uses these investments to enhance its ecosystem, secure supply chains, and protect its CUDA moat, with 106% revenue growth to $96.2 billion in its fiscal second quarter.
